Well, here’s something that will not come as a surprise…
Boeing has filed yet another patent, this time for “a system and method for generating electricity from acoustic energy from an aircraft on a runway.”
Essentially, Boeing wants to harness the roar of a jet’s engine and turn it into energy, another wild but innovative idea from the company.
MIT’s Ask An Engineer took on the question of turning sound into energy, and wrote:
What the human ear perceives as clanging cacophony—the roar of a train engine or the whine of a pneumatic drill—only translates to about a hundredth of a watt per square meter. In contrast, the amount of sunlight hitting a given spot on the earth is about 680 watts per meter squared.
Basically, while the idea is an intriguing one, it doesn’t appear to be viable when compared to solar or other energy sources currently available.
